-Changed the limits of the server room alarm to fix Issue 1143.

-Changed the singularity code a bit. Checking for the last movement had some problems, I changed it around. It fixed Issue 1121.
-In addition of this, the singularity will now move diagonally. It doesn't get stuck in the corners of the field now.
-Mimics which are structures, have density and anchored will be able to knockdown people and be twice as strong.
-Doubled the amount of times the staff of animation can fire before needing to recharge, since it had to shoot way more than the staff of change to be effective.
